This command is used to generate Snow Loads using previously specified Snow load definitions. This input should be a part of a load case.
General Format
SNOW LOAD
_flr_groupTYPE j CS f1 { BALANCED | UNBALANCED } { OBSTRUCTED | UNOBSTRUCTED } { MONO | HIP | GABLE }
Where:
| Parameter | Default Value | Description |
|---|---|---|
| _flr_group | - | The members that form the roof and that are to be loaded by snow load must be listed in a floor group (See TR.16 Entities as Single Objects). |
| TYPE j | - | The type number of previously defined snow load system. |
| CS f1 | 0.0 | Roof Slope factor (CS). For sloped roofs, the roof slope factor is described in section 7.4 of the SEI/ASCE-7-02. A value of 0 indicates that the roof is horizontal. |
| BALA or UNBA | BALA | Balanced or unbalanced snow load. Default is balanced. These terms are described in section 7.6, and figures 7.3 and 7.5 of ASCE 7-02. |
| OBST or UNOB | UNOB | Obstructed or unobstructed. |
| MONO or HIP or GABLE | NONO | Roof geometry type. |
Use as many floor groups and types as necessary in each load case.
